Description

Water airship

Technical Field

The invention relates to the technical field of water vehicles, in particular to a water airship.

Background

Speed is an important indicator for measuring the vehicle, and the importance of the speed of the ship as the main water vehicle is self-evident. In order to improve the ship speed, those skilled in the art continuously try and innovate and invent a hovercraft, a hydrofoil ship and a ground effect wing ship, but the ships have the problem that although the ship speed is improved, when the ships travel at a high speed, the ships with small draft can be lifted off the water surface to fly at an ultra-low altitude and a high speed, so that the resistance is increased.

Disclosure of Invention

In order to overcome the technical problems of the prior art, the invention provides a water airship. The specific technical scheme is as follows: the ship comprises a ship body, wherein the cross section of the ship body is in an inverted T shape, the transverse of the T shape is a wide and never-sinking floating body, and the vertical of the T shape is a long and narrow cabin; the floating body is of a bottom flat structure, and the cabin is of a top flat structure; the head of the ship body and the tail of the ship body are of pointed round structures, the front vertical surface of the cabin and the front vertical surface of the floating body are both vertically arranged, the front vertical surface of the cabin can form a hard sail, the head of the cabin is provided with a pneumatic driving device, the pneumatic driving device comprises an air inlet, and the head of the ship body and the floating body enclose an airflow channel communicated with the air inlet; and the tail part of the floating body is provided with a water spraying driving device with a steering device and a backing device.

In the technical scheme, the cross section of a ship body is in an inverted T shape, the transverse of the T shape is a wide and never-sinking floating body, and the vertical of the T shape is a long and narrow cabin; after the displacement and the length of the ship are determined, the width of the never-sinking floating body is increased, the balance is better, the draught is reduced, the pressure difference peak value of the head water and the tail water under the water of the ship is reduced, and the peak resistance is reduced. The cabin is long and narrow, and the width reduces, and the focus is in the centre, and the equilibrium is better, thereby the wind-break area of part on water reduces air resistance.

The never-sinking floating body is designed to be flat at the bottom, and the cabin is designed to be flat at the top, so that the lifting force or pressure generated during running can be avoided to cause the rising and falling of the bow and the stern, thereby increasing the wind-intercepting and water-intercepting area and increasing the resistance.

The pneumatic driving device is used for pumping air upwards from the front lower part of the bow and then pushing the air backwards, and the air pressure of the bow is reduced while forward power is obtained, so that the resistance is reduced and the power is increased; meanwhile, power for keeping the course is provided for the bow, and the wind and wave resistance of the ship is enhanced. The tail part of the floating body is designed into a sharp round structure (formed by a semicircle and a part enclosed by three tangent equal circles), and the front vertical surface is vertical. When the ship moves forward, the distances from the water at the two circle centers behind the floating body to each point at the stern are equal, so that the time for supplementing the water to the holes left by the ship moving forward is equal, the vortex and the turbulence are not easy to generate, and the resistance is reduced; similarly, the cabin is designed to be a tail tip circle, and the resistance can be reduced.

And the tail part of the floating body is provided with a water spraying driving device with a steering device and a backing device. The advantages of flexible steering and large water spraying driving thrust are achieved. The advantages of large water thrust and fast gas thrust are fully exerted by low-speed water spraying driving and high-speed water spraying and pneumatic driving; a water craft can travel at speeds of several hundred knots.

Further, the floating body is of a bottom flat structure, and the cabin is of a top flat structure. The problem that lift force or pressure generated during running causes the ship head and the ship tail to rise and fall, so that the wind-intercepting and water-intercepting area is increased and the resistance is increased is avoided.

Further, the gas driving device comprises a propeller, an axial flow fan and a jet engine. The gas is pumped upwards from the front lower part of the head of the cabin and then pushed backwards, and the head air pressure of the cabin is reduced while the forward power is obtained, so that the resistance is reduced and the power is increased; meanwhile, power for keeping the course is provided for the bow, and the wind and wave resistance of the ship is enhanced.

Furthermore, the tip circle structure is by 3 be the reciprocal triangle distribution and tangent two circle shears on the horizontal direction in the equal diameter circle except that the part of looks tangent point, and 3 rd circle shear is enclosed except that the remaining part behind its semicircle and is formed.

Furthermore, an inverted U-shaped flow guide device is arranged below the air inlet in front, two end feet of the inverted U-shaped flow guide device are communicated with the floating body, and the inverted U-shaped flow guide device can ensure that air cannot enter from the upper side, the left side and the right side.

Furthermore, the inverted U-shaped flow guide device, the head of the cabin and the floating body form the gas channel, and the gas channel is gradually reduced from the opening of the inverted U-shaped flow guide device to the inside. Thereby airflow channel diminishes gradually and makes the gaseous velocity of flow crescent, and atmospheric pressure diminishes gradually, and the resistance diminishes gradually, has improved step-down drag reduction effect to reduce bigger resistance and obtain bigger power. At the bow, the hold is both a hold and a part of the bleed passage; the floating body never sinks and is a part of the floating body and the air exhaust channel, and the function of reducing resistance and increasing power can be achieved.

Furthermore, the floating body is of a steel-glass fiber reinforced plastic-foam-wood plate-glass fiber reinforced plastic structure, the steel pipe is welded with a keel, the bottom and the peripheral wall are welded by steel plates, the glass fiber reinforced plastic is pasted, the steel plate is filled with foam, the wood plate is covered for fixing, the steel plate is sealed by glue, and finally the glass fiber reinforced plastic is pasted. When in use, the floating body can be sprinkled with sand to prevent slipping. The steel structure is firm; the glass fiber reinforced plastic has good corrosion resistance; the foam is filled never to sink and is not afraid of being broken by collision; the wood board is covered with the glue seal, so that the difficult problems that the wood board cannot be welded and cannot be directly pasted with glass after being filled with foam are solved. The floating body made of the alloy material has the advantages of firm structure, good corrosion resistance, no fear of being broken, no sinking and high safety performance.

Furthermore, a plurality of water spray driving devices are installed on two sides of the head of the ship body, and a water suction port of each water spray driving device is located below the head of the ship body and specifically located below a pointed end of the pointed circular structure. The water spraying driving device absorbs water from the lower part of a part enclosed by three tangent equal circles of a head sharp circle, so that the water pressure in front of the ship head can be reduced, the resistance is reduced, and higher power is obtained.

Furthermore, a periscope or a perspective mirror is arranged above the head of the floating body. The periscope or the perspective mirror solves the problem that the sight of a driver is blocked.

Compared with the prior art, the invention has the beneficial effects that:

(1) when the ship travels at high speed, the problem that the ship with small draft is lifted off the water surface, the ship flies at ultralow altitude and high speed, and the resistance is increased is mainly caused by the air pressure difference between the bow and the stern instead of the water pressure difference. The method comprises the following steps: the ship has both an underwater part and an above-water part. When the ship runs at high speed, the resistance mainly comes from the water pressure difference and the air pressure difference between the fore and the aft of the ship. Obviously, when the speed is increased continuously, the water pressure and the air pressure at the stern are close to 0; that is, the head and tail gas pressure difference peak value of the water part is close to one atmosphere (about 10 meters water column); and the peak value of the pressure difference between the head water and the tail water under the water is determined by the draught of the ship. The draft is 1 meter, the average water pressure at the bow is one twentieth of the atmospheric pressure (the water pressure at 0.5 meter underwater is the average water pressure); the draft is 2 meters for example, the average water pressure at the bow is one tenth of the atmospheric pressure (the water pressure at 1 meter under water is the average water pressure); the draft is 10 meters, and the average water pressure at the bow is only half of the atmospheric pressure (the water pressure at 5 meters underwater is the average water pressure). Thus, the resistance of a ship traveling at high speed, particularly a ship having a low draft, is mainly due to the differential pressure of the air at the bow and stern, not the differential pressure of the water. The water airship of the invention is composed of a never sinking floating body, which can avoid the ship from being lifted off the water surface when the ship travels at high speed, and can reduce the draught depth of the ship, ensure the balance and improve the safety. In addition, the invention is driven by a mode that the head air drives the tail to spray water, and the bow is provided with the air injection driving device which not only can obtain forward power, but also can pump away the air at the head of the cabin, so that the air pressure at the bow is reduced, and the peak resistance is further reduced.

(2) The ship body is of a structure with a sharp head, a round tail, a flat bottom, a flat top and a vertical front vertical surface, can reduce resistance, avoid generating lift force and provide heading power for the ship head so as to improve the wind and wave resistance of the ship; the low-speed water spraying driving and the high-speed water spraying air driving fully play the advantages of large water thrust and fast air thrust.

(3) The watercraft of the present invention can travel at speeds of several hundred knots. Firm structure, good corrosion resistance, no fear of being broken and never sinking.

The method comprises the following steps: the ship has both an underwater part and an above-water part. When the ship runs at high speed, the resistance mainly comes from the water pressure difference and the air pressure difference between the fore and the aft of the ship. Obviously, when the speed is increased continuously, the water pressure and the air pressure at the stern are close to 0; that is, the head and tail gas pressure difference peak value of the water part is close to one atmosphere (about 10 meters water column); and the peak value of the pressure difference between the head water and the tail water under the water is determined by the draught of the ship.
